Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In systems where multiple controlled objects operate in parallel, wasted time due to waiting or delays leads to inefficiencies in power consumption and cycle time, as existing control devices do not effectively utilize or adjust for these periods.
Innovation Solution
A control device with an analysis unit, control unit, adjustable interval detection unit, wasted time detection unit, and speed adjustment unit that analyzes control programs, detects wasted time, and adjusts speed or acceleration in adjustable intervals to reduce waiting or delay times, thereby optimizing power consumption and cycle times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wait control is performed to make controlled objects wait for each other for coordinated operation, then coordination between parallel paths is improved, but wasted time increases
Solution Approach 1:
The control device predicts wasted time before execution by analyzing control programs and identifying wait commands and their targets. This preliminary analysis allows the system to prepare speed adjustment parameters in advance, reducing actual waiting time during execution while maintaining coordination requirements.
Solution Approach 2:
The invention dynamically adjusts the speed of controlled objects based on predicted wasted time. By varying speed parameters in real-time according to the analyzed wait commands and their timing, the system optimizes coordination while minimizing idle waiting periods, transforming a static wait control into a dynamic optimization process.
2Productivity
If speed or acceleration is adjusted in adjustable intervals to reduce wasted time, then productivity is improved, but power consumption increases
Solution Approach 1:
The control device changes speed and acceleration parameters dynamically based on the analyzed control program and predicted wasted time. By adjusting these parameters only in identified adjustable intervals and only when necessary to reduce wasted time, the system improves productivity while minimizing the energy penalty associated with speed changes.
3Productivity
If the control program continuously runs after executing a command for calling a peripheral device, then operational continuity is maintained, but wasted time increases when blocks cannot be executed
Solution Approach 1:
The control device uses feedback from the analyzed control program to identify wait commands and their targets, then uses this information to predict wasted time and adjust speed parameters accordingly. This feedback mechanism allows the system to maintain operational continuity while compensating for inevitable waiting periods through proactive speed adjustment.
